GB Remanufacturing 7-007 Fuel Injector High Pressure Line for Duramax - LB7

The GB Remanufacturing 7-007 is a high-pressure fuel injector line designed specifically for Duramax LB7 diesel engines. This critical fuel system component addresses a common contamination issue that can lead to premature injector failure during service.

Key Features:

• Prevents contamination during injector service and replacement
• Meets or exceeds OE performance specifications for sealing and burst pressure
• Premium construction helps eliminate corrosion-related injector failures
• Direct replacement for worn or corroded original fuel lines

A frequent problem on LB7 engines is contamination of fuel fittings that occurs when corrosion forms between the line and injector nut. During injector removal or installation, this corrosion can fall directly into the injector, causing damage and failure. Replacing the high-pressure fuel line during injector service is highly recommended as a preventive measure to protect your new or serviced injectors from contamination damage. GB premium fuel lines are engineered to deliver reliable sealing performance and withstand high fuel system pressures for long-lasting durability.
